How early should I arrive at O’Hare for a Turkish Airlines international flight?

For international Turkish Airlines flights departing from O’Hare, it’s recommended to arrive at least three hours prior to departure. This allows ample time for check-in, baggage drop, and security screening, which can be time-consuming at a busy international terminal like O'Hare. Passengers traveling with checked luggage or requiring special services should especially adhere to this guideline. Turkish Airline Terminal Ohare is a hub for many international flights, so security lines can sometimes be long. Early arrival also gives you time to explore the terminal’s amenities, especially if you have access to the Turkish Airlines Lounge.
